Definitions

  • the expensive jaw mount and jaws, and the control wire are readily removable from the support cable so the cable can be discarded, and the more expensive mount, jaws and control wire, may be cleaned and reused. Only the less expensive support cable need be replaced.
  • Biopsy forceps for endoscopic usage characteristically include a pair of pivotally mounted jaws mounted at the distal end of a tubular support member.
  • Rigid instrument constructions utilize a rigid tube for supporting the jaws.
  • Flexible constructions utilize a flexible tubular cable for supporting the jaws.
  • Rigid instruments of this type tend to be more expensive, and are intended to be re-used. They are designed for this, and are rather easily cleaned and sterilized for their next use.
  • a biopsy forceps includes a flexible tubular support cable with an internal passage.
  • the support cable has a proximal end and a distal end.
  • a jaw mount is mounted to the support cable at its distal end. It supports a pair of pivoted jaws having sharp cutting edges that are moved toward and away from one another by a control wire.
  • the control wire passes through the passage in the support cable. It connects to the jaws at the distal end.
  • the support cable and control wire are attached to actuation means such as a scissor type grip, or a thumb loop and handle. Both are well-known means for moving a control wire in a support cable.
  • the support cable is a tightly wound helical spring. It is made of a suitable metal, and of such dimensions that it can readily bend to conform to bends in a cavity into which it is inserted, such as the colon. Inherently, its outer surface has a helically shaped groove and crest, much like a helical thread. Because the support cable is inherently springy in the sense of deflectibility, it can be compressed radically (lengthening slightly to enable this), and will exert a spring-back force against a body tending to compress it.
  • the mount has a tubular socket whose internal diameter is suitable smaller than the outermost diametrical dimension of the support cable's convolutions, and can be placed over them, then the jaw mount will be reliably retained.
  • the socket makes an interference fit with the convolutions, and is placed over them by means of rotating it around the cable's axis so that the convolutions tend to "thread" their way into the socket even though the socket has no threads.
  • it is cylindrical. Removal is the reverse--the mount is simply turned in the opposite direction.
  • the jaws, jaw mount, and control wire which are readily cleaned, can be re-used indefinitely, requiring only a new support cable each time.
  • the instrument is taken apart to be cleaned and the jaw mount can readily be applied to a new support cable.
  • FIG. 1 is a side view of presently-preferred embodiment of the invention
  • FIG. 2 is an axial cross-section of the portion marked "2" in FIG. 1;
  • FIG. 3 is a fragmentary view showing the embodiment of FIG. 1 disassembled.
  • a biopsy forceps 10 includes a support cable 11.
  • the support cable has a distal end 12 and a proximal end 13.
  • the support cable is a flexible metal helically wound wire structure having coil convolutions 15 with a groove 16 between adjacent convolutions, and a curved crest 17 at the maximum diameter of the convolutions.
  • the convolutions abut each other closely, but they are not attached to one another.
  • the support cable can lengthen, and its diameter can be reduced. In this invention, the diameter is reduced, and the support cable lengthens locally and slightly to enable it.
  • a jaw mount 20 has a socket with an internal wall 21.
  • Wall 21 is cylindrical, although it may also have a short bell-mouth section 22 or internal bevel to provide a lead-in for the cable.
  • the diameter 23 of the cylindrical portion is smaller than the maximum diameter 24 of the convolutions of the support cable.
  • Jaws 30, 31 are hingedly mounted to the jaw mount. They have respective sharp cutting edges 32, 33, which when brought against or past each other will cut the specimen loose.
  • each has a respective lever arm 34, 35 connected to a control wire 40.
  • the control wire extends through the passage in the support cable.
  • the instrument is assembled by inserting the control wire into the passage. Then, when the socket of the jaw mount reaches the distal end of the support cable, it is rotated while being axially pressed over the distal end. This will slightly compress the coiled structure, and the cable passes along the support cable very much like a threaded movement, except that there is no thread.
  • Retention of the jaw mount is quite reliable, because of the substantial spring-back force exerted radially by the convolutions against the inside wall of the jaw mount.
  • the amount of compression varies with the dimensions and characteristics of the support cable.
  • a cable having an external diameter of about 2 mm will generally be compressed diametrically by about 5%, the support cable being a wound stainless steel wire.
  • the dimensions of the mount will be selected so its outer diameter will be about equal to that of the support cable.
  • the support cable will have a coating 41 (FIG. 3) of Teflon or some other plastic. It will be stripped from the cable over the inserted length.
  • the outer diameter of the mount and of the layer will be approximately equal.
  • a flexible biopsy forceps can be provided whose most expensive parts can be cleaned, and which requires the replacement only of a relatively inexpensive length of cable when it is to be cleaned and reused.
